CombiMatrix Corporation

IRVINE, Calif., May 6, 2013 (GLOBE NEWSWIRE) -- CombiMatrix Corporation (Nasdaq:CBMX), a molecular diagnostics company performing DNA-based testing services for developmental disorders and cancer, announced today that it has entered into an agreement to issue securities in a private placement transaction to certain accredited investors that will result in proceeds to the Company totaling $2.4 million, to be received in two tranches, with the first tranche expected to close within two days and the second tranche to close following stockholder approval, subject to customary closing conditions.

The financing is through the sale of Series C convertible preferred stock with the first tranche having an initial conversion price of $3.05 per common share, subject to adjustment therein, and warrants to purchase 125% of the number of shares underlying the Series C convertible preferred stock at an initial exercise price of $3.77 per share. The Series C convertible preferred stock accrues an annual dividend of 6%, which rate shall increase by 1% per year, not to exceed 10%. The warrants are not exercisable for six months and are exercisable for five years thereafter. The preferred stock is not convertible until stockholder approval has been obtained. Upon closing of the first tranche, the Company will receive gross proceeds of $1.2 million from the investors. The Company intends to file a proxy statement within the next few days to seek stockholder approval to close the second tranche for proceeds of $1.2 million from the investors. Pursuant to a registration rights agreement, the Company will file a resale registration statement to register the shares underlying the preferred stock and warrants issued in the first tranche within 15 days following the closing.

CombiMatrix President and CEO Mark McDonough said, "The two recent financings we have secured in the past two months enable us to substantially improve our balance sheet and concurrently invest in the prenatal market where we are finding commercial success. We have shown triple digit volume growth in the past two quarters in our core prenatal testing market and the addition of this capital will help us continue to ramp the business on our path to profitability."
